Jose Canseco was nervous and scared about showing up to the reunion for the 1989 World Series champion A's this weekend, according to an ESPN.com report.

Until Friday, Canseco had not been back to the Coliseum since his playing days ended and he wrote his infamous book that alleged rampant use of performance-enhancing drugs throughout baseball. He had no idea how his former teammates, coaches and fans would receive him, or if they would receive him at all.

"I'm kind of putting myself out there in the most vulnerable state possible," said the 50-year-old Canseco, who was still looking big and buff in his white A's jersey.
